- pressing members 54 a and 54 b are respectively provided on a rear side and a front side of the first guide 50 .
- the pressing members 54 a and 54 b are slidable in an up/down direction (the direction of the arrow P in FIG. 7 ) of the first guide 50 and are biased in an upward direction by biasing means 55 a and 55 b that are compression springs or the like.
- V-shaped positioning portions 56 a and 56 b are respectively provided on a rear side and a front side of the apparatus main body.
- a hole portion 57 which extends in a direction of upward/downward movement of the first guide 50 and which has a long, round hole shape is provided on the rear side.
- the process cartridge 7 is respectively provided with receiving portions 14 g 1 and 14 g 2 on a rear side and a front side of the cleaning unit 13 .
- R-shaped restricting portions 14 h 1 and 14 h 2 are respectively provided on the rear side and the front side of the cleaning unit 13 .
- a cylindrical rotation-preventing boss 14 j is provided on the rear side of the cleaning unit 13 .
- the pressing members 54 a and 54 b press the receiving portions 14 g 1 and 14 g 2 upward due to biasing forces of the biasing means 55 a and 55 b .
- the restricting portions 14 h 1 and 14 h 2 of the cleaning unit 13 abutting against the positioning portions 56 a and 56 b of the main body 100 and the rotation-preventing boss 14 j engaging with the hole portion 57 , a position of the process cartridge 7 with respect to the main body 100 is determined.
- the cleaning frame body 14 is provided with the opening 14 c through which the laser light 3 a for exposing the photosensitive drum 1 can pass.
- the opening 14 c is provided in a direction in which the cleaning unit 13 and the developing unit 4 oppose each other (a direction of an arrow N in FIG. 1 ).
- an electrostatic latent image in accordance with the image information is formed on the photosensitive drum 1 .
- the laser light 3 a passes through the opening 14 c and is irradiated on the photosensitive drum 1 .
- the first guided portion 14 d is arranged on the side of the developing unit 4 so as to straddle the laser light 3 a .
- the cleaning frame body 14 includes a portion on a side far from the photosensitive drum 1 (a first frame body portion) and a portion on a side close to the photosensitive drum 1 (a second frame body portion) approximately across the opening 14 c , and the first guided portion 14 d is provided in the first frame body portion.
- the second guided portions 14 e 1 and 14 e 2 are provided in the second frame body portion.
- the cleaning frame body 14 is configured to include a portion in which the first guided portion 14 d is provided, a portion in which the second guided portions 14 e 1 and 14 e 2 are provided, and a connecting portion which connects the two portions across an optical path of the laser light 3 a .
- the first frame body portion and the second frame body portion are positioned so as to sandwich the optical path of the laser light 3 a , and the first frame body portion is positioned on a same side as the developing unit 4 with respect to the optical path of the laser light 3 a .
- the first frame body portion is positioned on an opposite side across the optical path of the laser light 3 a with respect to the developing unit 4 of an adjacent process cartridge 7 (another developing cartridge).
- a frame body dimension in a direction in which the process cartridges 7 are adjacent to each other can be reduced.
- a width of the process cartridge 7 in a direction in which the cleaning unit 13 and the developing unit 4 oppose each other can be reduced at the opening 14 c and in a region where the opening 14 c is separated from the center of the photosensitive drum 1 .
- the process cartridges 7 can be downsized and adjacent intervals of the process cartridges 7 that are adjacent to each other can be reduced. Accordingly, a reduction in mounting spaces of the plurality of process cartridges 7 in the apparatus main body can be performed and downsizing of the apparatus can be achieved.
- the opening 14 c has a trapezoidal shape when viewed from a direction in which the cleaning unit 13 and the developing unit 4 oppose each other (the direction of the arrow N in FIG. 1 ). This is a shape that enables the laser light 3 a to be irradiated in a printable region J on the photosensitive drum 1 .
- the opening 14 c is configured so that the width of the opening 14 c in a scanning direction in an irradiation range of the laser light 3 a becomes greater gradually toward a side of the photosensitive drum 1 from a side of a light source of the laser light 3 a .
- a size of the connecting portion which connects a portion on one side and a portion on the other side of the opening 14 c of the cleaning frame body 14 can be secured and strength of the frame body can be secured while ensuring that the optical path of the laser light 3 a is not obstructed.
- the opening 14 c is given a trapezoidal shape in the present embodiment, this is not restrictive.
- the opening 14 c may have any shape such as a rectangle as long as the opening is large enough to enable the laser light 3 a to be irradiated in the printable region of the photosensitive drum 1 .
- the developing unit 4 is exposed to an exterior near center in the longitudinal direction. Accordingly, only the developing unit 4 exposed to the exterior near center in the longitudinal direction can be made graspable. By making only the developing unit 4 graspable as in the case of the embodiment, rotational movements of the developing unit 4 and the cleaning unit 13 can be prevented during handling by the user. As a result, operability is improved.
